A generalized density-modulated twist-splay-bend phase of banana-shaped particles
Nature Communications, 2021 The so-called twist-bend and splay-bend nematic liquid crystal phases are important concepts for studying bent-core mesogens. Chiappini et al. use a theory/simulation approach to suggest that the transition proceed via a twist-splay-bend phase which may ...

Twisting phase and intensity of light with plasmonic metasurfaces [PDF]
Scientific Reports, 2018 AbstractTwisting light in both phase and intensity has recently drawn great interests in various fields related to light-matter interactions such as optical manipulation of particles and quantum entanglement of photons. Conventionally, bulky optical components are required to produce such twisted optical beams, which significantly limits their ...

Bifurcation analysis of the twist-Freedericksz transition in a nematic liquid-crystal cell with pre-twist boundary conditions [PDF]
, 2009 Motivated by a recent investigation of Millar and McKay [Mol. Cryst. Liq. Cryst., 435, 277/[937]-286/[946] (2005)], we study the magnetic field twist-Fr´eedericksz transition for a nematic liquid crystal of positive diamagnetic anisotropy with strong ...

Twist grain boundaries in cubic surfactant phases [PDF]
The Journal of Chemical Physics, 2009 Twist grain boundaries in bicontinuous cubic surfactant phases are studied by employing a Ginzburg–Landau model of ternary amphiphilic systems. Calculations are performed on a discrete real-space lattice with periodic boundary conditions for the lamellar Lα, gyroid G, diamond D, and the Schwarz P phases for various twist angles.

Optimal Segment Control of Active Twist Rotor for Power Reduction in Forward Flight
Applied Sciences, 2021 The segment control of active twist rotor is investigated to evaluate the effectiveness in rotor power reduction. A numerical model for predicting the isolated rotor power and loads in steady level flights is deployed and validated. A parametric sweep of

A fibre forming smectic twist-bent liquid crystalline phase [PDF]
, 2015 We demonstrate the nanostructure and filament formation of a novel liquid crystal phase of a dimeric mesogen below the twist–bend nematic phase. The new fibre-forming phase is distinguished by a short-correlated smectic order combined with an additional ...

Formulation of the twisted-light–matter interaction at the phase singularity: The twisted-light gauge [PDF]
Physical Review A, 2015 Twisted light is light carrying orbital angular momentum. The profile of such a beam is a ring-like structure with a node at the beam axis, where a phase singularity exits. Due to the strong spatial inhomogeneity the mathematical description of twisted-light--matter interaction is non-trivial, in particular close to the phase singularity, where the ...
